    <!-- After you have all the components blocked out on the canvas, you're ready to start adding wires. Select the <b class=propertie>"Edit"</b> Tool (<img class="icontxt" src="../../../../icons/1616/toolselect.png" alt="#########">). When the cursor is over a point that receives a wire, a small green circle will be drawn around it. Press the <b class="tkeybd">left mouse button</b> there and drag as far as you want the wire to go. -->
    在画布上放置好所有元件后，您就可以开始添加导线了。 选择
    <b class="propertie">
     "Edit"
    </b>
    工具(
    <img alt="#########" class="icontxt" src="../../../../icons/1616/toolselect.png"/>
    )。 当光标位于接收导线的点上时，将在其周围绘制一个绿色的小圆圈。 按下
    <b class="tkeybd">
     left mouse button
    </b>
    ，然后将导线拖动到您想要的位置。

    <!-- Logisim is rather intelligent when adding wires: Whenever a wire ends at another wire, Logisim automatically connects them. You can also "extend" or "shorten" a wire by dragging one of its endpoints using the <b class=propertie>"Edit"</b> tool (<img class="icontxt" src="../../../../icons/1616/toolselect.png" alt="#########">). -->
    Logisim-evolution在添加导线时相当智能：只要一根导线在另一根导线上结束，Logisim-evolution就会自动连接它们。 您还可以使用
    <b class="propertie">
     "Edit"
    </b>
    工具 (
    <img alt="#########" class="icontxt" src="../../../../icons/1616/toolselect.png"/>
    )。
   </p>
   <p>
    <!-- Wires in Logisim must be horizontal or vertical. To connect the upper input to the NOT gate and the AND gate, then, I added three different wires. -->
    Logisim-evolution中的导线必须是水平或垂直的。 然后，为了将上部输入连接到非门和与门，我添加了三根不同的导线。
   </p>

   </p>
   <p>
    <!-- Logisim automatically connects wires to the gates and to each other. This includes automatically drawing the circle at a <i>T</i> intersection as above, indicating that the wires are connected. -->
    Logisim-evolution自动将导线连接至门以及彼此之间。这包括在上面的
    <i>
     T
    </i>
    交叉点处自动绘制圆圈，表明导线已连接。
   </p>
   <p>
    <!-- As you draw wires, you may see some blue or gray wires. Blue in Logisim indicates that the value at that point is "unknown," and gray indicates that the wire is not connected to anything. This is not a big deal as you're in the process of building a circuit. But by the time you finish it, none of your wires should be blue or gray. (The unconnected legs of the OR gate will still be blue: That's fine.) -->
    当您绘制导线时，您可能会看到一些蓝色或灰色的导线。 Logisim-evolution 中的蓝色表示该点的值“未知”，灰色表示电线未连接到任何东西。 这不是什么大问题，因为您正在构建电路。 但当你完成它时，你的导线都不应该是蓝色或灰色的。 （“或”门未连接的端仍为蓝色：这是没问题的。）
   </p>
   <p>
    <!-- If you do have a blue or a gray wire after you think everything ought to be connected, then something is going wrong. It's important that you connect wires to the right places. Logisim draws little dots on the components to indicate where wires ought to connect. As you proceed, you'll see the dots turn from blue to light or dark green. -->
    如果所有东西连接了之后，还有一根蓝色或灰色的导线，那么就说明出了问题。 将导线连接到正确的位置非常重要。 Logisim-evolution在元件上绘制小点来指示电线应连接的位置。 当您继续操作时，您会看到这些点从蓝色变成浅绿色或深绿色。
   </p>
   <p>
    <!-- Once you have all the wires connected, all of the wires you inserted will themselves be light or dark green. -->
    连接完所有导线后，处于连接状态的所有导线本身将呈浅绿色或深绿色。
